SOLUTION: A handle device in which a stop member is locked to a receiving member by closing a cover and rotating the handle, wherein a lock hole is formed in the handle, and the lock is elastically biased toward the handle. The handle is locked by inserting the pin into the lock hole of the handle, and the locked state of the handle is released by pushing the lock pin back with the release button.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a handle device for a cover of a photographic processing apparatus such as a developing machine or a printer.

[0002]

2. Description of the Related Art A photographic processing apparatus of this type is provided with a cover a for maintenance and inspection as shown in FIG. 3, and a handle b for opening and closing the cover is attached to the cover a. The handle b is provided with a lock device for preventing light fogging of the photosensitive material due to the cover a being opened carelessly. The lock device is operated by inserting the key d into the key hole c of the handle b. This was done by turning d.

However, in the case of such a conventional handle device,
A lock operation must be performed with the key b separately from the handle b, and the cover a cannot be opened due to the loss or damage of the key b, or it takes time to open the cover a in an emergency.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object the following.
It is an object of the present invention to provide a handle device for a cover of a photographic processing apparatus, in which a handle can be locked without using a key and a locked state of the handle can be quickly released even in an emergency.

[0005]

SUMMARY OF THE INVENTION A handle device for a cover of a photographic processing apparatus provided to solve the above-mentioned problems includes:
A handle provided on the cover side, a stop member attached to the handle, and a receiving member provided on the photo processing apparatus main body side are provided, and the stop member is locked to the receiving member by closing the cover and rotating the handle. In a handle device for a cover of a photo processing device, a lock hole formed in the handle, and elastically biased toward the handle, and
A lock pin that fits into the lock hole of the handle when the stop member is locked to the receiving member to lock the handle,
And a release button for pushing back the lock pin fitted into the lock hole of the handle to release the locked state of the handle.

[0006]

FIG. 1 is a sectional view of a handle device for a cover of a photographic processing device such as a developing machine or a printer, and FIG. 2 is a sectional view for explaining the operation of the handle device. Reference numeral 1 in the figure denotes a cover of the photo processing apparatus, which opens and closes an opening A1 for maintenance and inspection provided in the main body A of the photo processing apparatus. It is pivotally connected by a hinge (not shown).

[0007] A handle 2 is provided on the cover 1, and a stopper 3 is integrally attached to the handle 2. A receiving member 4 is attached to an inner wall surface near the opening A1 of the main body A of the photographic processing apparatus.
When the handle 2 is rotated in a state in which the closing member 3 is closed,
Are locked to the receiving member 4 so that the cover 1 cannot be opened (FIG. 1).

A mounting hole 5 is formed in the cover 1, and a screw insertion hole 6 is provided around the mounting hole 5. Reference numeral 7 in the figure denotes a disk-shaped handle bearing. A handle shaft hole 7a is provided at the center of the handle bearing 7, and a boss 7b is formed at the periphery of the handle shaft hole 7a. Further, a pin storage hole 7c is formed on the back surface of the periphery of the handle bearing 7, and a pin protrusion hole 7d is formed on the front surface side.
And are coaxial with each other. In addition, a screw hole 7e is provided on the back surface of the handle bearing 7.

Then, the boss portion 7b of the handle bearing 7 is fitted into the mounting hole 5 of the cover 1, and the screw 13 is screwed into the screw hole 7e of the handle bearing 7 via the screw insertion hole 6 of the cover 1. Thus, the handle bearing 7 is fixed to the cover 1.

Reference numeral 8 in the figure denotes a lock pin, which is provided at its base end with a retaining collar 8a. The lock pin 8 is slidably housed in the pin housing hole 7c, and
It is projected from the pin projection hole 7d while being urged by the spring body (coil spring) 14.

The handle 2 is constructed by extending a cylindrical cover 2b from the periphery of a disk-shaped main body 2a. A mounting hole 2c is formed in the center of the main body 2a. A large-diameter lock hole 2d is provided on the back side of the main body 2a.
A small-diameter release pin storage hole 2e is formed in the front surface side of the main body 2a, and the lock hole 2d and the release pin storage hole 2e communicate with each other and are located coaxially.

Reference numeral 9 in the drawing denotes a release pin, which is provided at its base end with a retaining collar 9a. The release pin 9 is slidably received in the release pin storage hole 2e of the handle 2, and the base end of the release pin 9 is located in the lock hole 2d.

Reference numeral 10 in the drawing denotes a handle shaft, which is a large-diameter shaft portion 10a and a small-diameter shaft portion 10b formed coaxially.
And a retaining collar 10 formed at the shaft end of the large-diameter shaft portion 10a.
c, the large-diameter shaft portion 10a and the small-diameter shaft portion 1
Screw holes 10d and 10e are formed in the shaft end surfaces of the shaft 0b. The large-diameter shaft portion 10a of the handle shaft 10 is fitted into the handle shaft hole 7a of the handle bearing 7, the small-diameter shaft portion 10b of the handle shaft 10 is fitted into the mounting hole 2c of the handle 2, and the retaining screw 11 is attached to the handle shaft. It is screwed into the screw hole 10e of the small diameter shaft portion 10b. Thus, the handle shaft 10 is supported by the handle bearing 7, and the handle 2 is fixed to the handle shaft 10.

The stopper member 3 is formed by bending a metal plate, and a screw insertion hole 3a is formed at an end of the stopper member 3. Then, the screw 12 is screwed into the screw insertion hole 3 of the stopper member 3.
screw hole 1 of large-diameter shaft portion 10a of handle shaft 10 through a
0d, the stop member 3 is attached to the handle shaft 1
It is fixed to 0.

Therefore, when the handle 2 is rotated,
The stop member 3 rotates together with the handle shaft 10.

FIG. 1 shows a state in which the stopper member 3 is engaged with the receiving member 4. At this time, the lock pin 8 is fitted into the lock hole 2 d of the handle 2 by the spring biasing force of the spring body 14. While the handle 2 is locked, the release pin 9 is pushed by the lock pin 8 and protrudes from the release pin storage hole 2e.

On the other hand, when the cover 1 is opened, as shown in FIG.
Push back the lock pin 8 fitted in
After the lock state is released, the handle 2 is rotated to remove the stop member 3 from the receiving member 4.

The configuration and position of the lock hole 2d, the lock pin 8 and the release pin 9 of the handle 2
There is no particular limitation as long as the handle 2 can be rotated while holding down. In this embodiment, the projecting position of the release pin 9 is set so that the locked state of the handle 2 can be released and the handle 2 can be rotated with one hand.

[0019]

As is apparent from the above description, according to the handle device of the cover of the photographic processing apparatus of the present invention, when the stop member is locked on the receiving member, the lock pin is fitted into the lock hole. The handle is locked and the handle is unlocked by pushing the lock pin back, eliminating the need for a lock key as in the past and opening the cover by pushing the lock pin. Because it is possible, it is possible to respond quickly even in an emergency.
