Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates in particular to a fixing mechanism for a cassette member that is removably installed in a device body, and hereinafter, the present invention relates to a cassette of a change dispensing device used in a vending machine, etc. This will be explained using a change cylinder as an example.

[Prior art] This type of cassette-type change cylinder was developed in 1983.
As described in Publication No. 57872, a fixing mechanism is known in which a change tube is locked by biasing a detachable lever supported by a fixed shaft with a coiled spring. .

[Problems to be solved by the invention] However, the above-mentioned fixing mechanism requires at least three parts: a fixing shaft, a lever for attaching and detaching, and a spring, so there are many parts and assembly work is not easy. There was a problem.

In view of the above-mentioned points, it is an object of the present invention to provide a cassette member in which the spring of the fixing mechanism can be formed integrally with other parts, thereby making it possible to reduce the number of parts.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes a fixing piece that is inserted into and removed from a recess in a device main body in a direction substantially perpendicular to the removal direction, and a fixing piece that is inserted into the recess. In a cassette member equipped with a fixing mechanism having a spring part that biases in the insertion direction, the spring part is formed into a ring shape from a synthetic resin having elasticity, and the elastic force in the radial direction of the ring-shaped spring part A feature of the present invention is that the fixing piece is biased by pressing the fixing piece.

[Function] According to the present invention, the spring part is made into a ring shape so that the fixing piece is biased by elastic force in the radial direction, so that it is difficult to use a spring that uses a conventional coil spring. The part and fixing piece can be integrally molded from synthetic resin.

[Examples] Examples of the present invention will be described below with reference to the drawings.

1, 2, and 3 are a front view, a side view, and a plan view, respectively, of a cassette-type change cylinder that is an embodiment of the present invention. In the figure, a protruding piece 1a is provided at the bottom of a cassette-type change cylinder 1, and this is inserted and fixed into a recess A of the main body of the coin sorting device. A fixing mechanism 2 integrally molded from synthetic resin is provided at the upper part to fix the device. The structure of the fixing mechanism 2 is made of elastic synthetic resin (for example, polyurethane).
A ring-shaped spring portion 2a is formed with
Stopper portions 2b and 2b' are provided above and below. A push-down part (operation part) 2c is provided on the spring part 2a, and a fixing piece 2d is further formed. This fixing mechanism 2 is
The vicinity of the upper fixed piece 2d is held from both sides by guide rails 1b provided on the change tube 1, and the spring portion 2a
The lower part of the change tube 1 is supported by a support piece 1c provided on the change cylinder 1. Then, the fixing piece 2d is inserted into the recess B of the coin sorting device body and fixed. Attaching and detaching the change tube 1 is easy. For example, in the case of detachment, press the push-down part 2c of the fixing mechanism 2 with your finger in the direction of arrow P (in the radial direction of the ring-shaped spring part 2a), which is almost perpendicular to the detachment direction R. ), the spring portion 2a is elastically deformed until the bending stopper portions 2b, 2b' come into contact with each other. At that time, the fixed piece 2d will come off from the recess B, so the change cylinder 1 can be removed by tilting the upper part of the change cylinder 1 in the direction of arrow R, then lifting it slightly upwards, and pulling out the protruding piece 1a from the recess A. can. For installation, the operation described above can be reversed. FIG. 4 shows the operating state of the fixing mechanism 2, with the left side showing a steady state and the right side showing a state where an external force is applied from the P direction.

[Effects of the invention] According to the invention as described above, the spring part is ring-shaped so that the fixing piece is biased by elastic force in the radial direction, and the spring part and the fixing piece are integrally molded from synthetic resin. This allows for a reduction in the number of parts and cost reduction compared to conventional products.

[Brief explanation of the drawing]

Figures 1, 2, and 3 are front, side, and plan views, respectively, of a cassette-type change tube that is an embodiment of the present invention, and Figure 4 is the operation of the fixing mechanism provided in the same change tube. It is a figure showing a state. 1: Cassette type change tube, 2: Fixing mechanism, 2a:
Spring part, 2d: Fixed piece, B: Recessed part of the coin sorting device main body. 〓〓〓〓〓
