JP-2026074500-A - Document scanning device
Abstract
[Problem] The objective is to prevent the document cover from closing even when strong force is applied to it. [Solution] The hinge 30 comprises a hinge shaft 72 provided in the housing, a hinge body 31 provided in the document cover and rotatable about the hinge shaft 72, a lock shaft 78 provided in the housing parallel to the hinge shaft 72, and a lock member 75 rotatable about the lock shaft 78. The lock member 75 has grooves 76 provided at two locations parallel to the lock shaft 78 and sandwiching the lock shaft 78. The hinge body 31 comprises a circumferential slit 34 that is narrower than the longitudinal length of the lock member 75 as viewed from the direction of the lock shaft 78 and wider than the width in the direction intersecting the longitudinal direction of the lock member 75, a first contact portion 35 provided radially outward from the lock shaft 78, and a second contact portion 36 provided radially inward from the lock shaft 78.

Claims (4)
- Housing and The housing comprises a document cover positioned on the upper surface of the housing and connected to the housing via a hinge so as to be openable and closable, The aforementioned hinge is, A hinge shaft provided in the housing, A hinge body provided on the aforementioned document cover and rotatable about the hinge axis, A locking shaft is provided in the housing parallel to the hinge shaft, The locking member comprises a locking member that is rotatable about the locking shaft, The locking member has grooves provided at two locations parallel to the locking shaft and sandwiching the locking shaft. The hinge body portion is, A slit along the circumferential direction, which is narrower than the longitudinal length of the locking member as viewed from the direction of the lock axis, and wider than the width in the direction intersecting the longitudinal direction of the locking member, A first contact portion provided radially outward from the locking shaft, It comprises a second contact portion provided radially inward from the locking shaft, When the document cover is closed, the locking member is housed in the slit. Subsequently, when the document cover is opened to the first angle, the first contact portion comes into contact with the groove portion of the locking member that has emerged from the slit, causing the locking member to rotate in the first direction. Subsequently, when the document cover is returned to a second angle smaller than the first angle, the second contact portion engages with the groove on the other side of the locking member, thereby locking the document cover. Subsequently, when the document cover is opened to the first angle, the first contact portion comes into contact with the locking member, causing the locking member to rotate further in the first direction. The document reading device is characterized in that, when the document cover is returned to the second angle, the second contact portion contacts the locking member, causing the locking member to rotate further in the first direction, the locking member to be housed in the slit, and the document cover to close.
- The document reading device according to claim 1, characterized in that the groove portion is formed in a V-shape.
- The document reading device according to claim 1 or 2, characterized in that the second contact portion is provided at the end of the wall surface on the hinge axis side of the slit.
- The document reader according to claim 1 or 2, characterized in that the document cover includes a document transport device that transports the document via a reading position.
Description
This invention relates to a document reading device. A flatbed document scanner equipped with a document cover that holds down the document placed on the contact glass is known (for example, Patent Document 1). The document cover is hinged to the rear of the contact glass and can be opened and closed using the hinge as a pivot point. Furthermore, a document scanner equipped with a document transport device on the document cover that transports the document via the scanning position of the document scanner is also known (for example, Patent Document 2).
