  In the lock structure disclosed in Patent Document 1, the lock is released by pulling the handle, and then the door can be opened by further pulling the handle. Accordingly, during this operation, the force acting on the handle portion acts on the holding member from the operation member via the pivot, and finally acts on the opening / closing door, and thus it is necessary to increase the strength of the portion where the force acts. was there. Specifically, since the operation member is supported by the holding member via the pivot, the support strength between the pivot and the holding member is increased, and the holding member is supported by fitting to the open / close door. It is required to increase the strength of the fitting portion.

  However, in the case where the holding member is fixed to the open / close door by fitting, even if the strength of the fitting portion is increased, a strong force is applied each time the handle portion is operated. There is room for improvement because the gaps may expand or break. In particular, when a relatively large assembly hole is formed in the opening and closing door and the holding member is fitted into this assembly hole, a structure for increasing the fitting strength while preventing the penetration of light is required. There was also room for improvement in this regard.

  It is an object of the present invention to maintain a closed door that is openable and closable with respect to a processing apparatus and to release the closed state by manual operation of the handle portion while preventing the penetration of light into the apparatus. It is in the point to be configured.

A feature of the present invention is that the processing device for processing the photosensitive material includes an operation means for maintaining the door in a closed state so as to be opened and closed, and releasing the closed state by human operation.

  With this configuration, the base is fixed to the opening part of the door, and after inserting the swinging member into the base, the support shaft is inserted into each through hole, so that the through hole of the shaft support part formed in the door The support shaft is inserted into the through hole formed in the base and the through hole formed in the swinging member. For example, even if an operation of pulling the handle portion strongly is performed, this operating force is transmitted through the support shaft. Therefore, it is transmitted directly to the door shaft support, and no strong force is applied between the base and the door. As a result, it is possible to firmly construct a structure in which the door that can be opened and closed in the processing apparatus is maintained in a closed state, and the closed state is released by human operation of the handle portion while preventing the penetration of light into the apparatus. did it.
