[0031]
[Effect of the embodiment]
Next, the operation of the drum-type symbol display device according to the embodiment will be described. The drum-type symbol display device 20 is configured so that the connector connection port 30a formed at the upper position on the rear side of the drive board 30 is exposed to the outside through the insertion hole of the rear case 24, and the lower position on the rear side of the drive board 30. Is inserted between the protrusions 24b, 24b of the rear case 24, and the rear side of the symbol display unit U is positioned and fixed. Further, the positioning protrusion 32c of the mounting base 32 attached to the drive board 30 is engaged with the groove 22b of the fluoroscopic display body 22, and the positioning recess 32b of the mounting base 32 is replaced with the protruding piece of the front case 25. By engaging with 25b, the front side of the symbol display unit U is positioned and fixed and held in the drum case 21 in an upright state. In this state, by rotating or stopping the stepping motor 38 disposed on the drive substrate 30, the design drum 34 connected to the stepping motor 38 via the connection fixing portion 39 is rotated and stopped. It is like that.
[0032]
Here, when the detection piece 46b of the index 46 formed on the connection fixing portion 39 passes between the light emitting portion and the light receiving portion of the detection sensor 48, the original position of the symbol provided on the peripheral surface of the symbol drum 34 is changed. Be recognized. Then, by controlling the amount of displacement of the stepping motor 38 from the original position of the symbol on the symbol drum 34, it becomes possible to stop and display a predetermined symbol at a corresponding position on each symbol stop line T.
[0033]
If the detection piece 46b is too long, the detection piece 46b and the other member will be bent when contacting the design drum 34, and an error will occur when the detection sensor 48 detects the error. In some cases, the original position of the symbol cannot be detected. Therefore, in the embodiment, by attaching the detection sensor 48 to the attachment portion 33 formed on the attachment base 32, the detection sensor 48 is brought close to the support portion 46a of the index 46, and the detection piece 46b of the index 46 is shortened. Since it did in this way, generation | occurrence | production of the bending etc. to the said detection piece 46b at the time of rotation of the said symbol drum 34 can be suppressed, and the original position detection of a symbol can be performed.
[0034]
The index 46 is formed on the connecting and fixing portion 39, and the index 46 is passed through a required passage 44 defined between the rear side of the reflector member 42 (illuminating device 41) and the stepping motor 38. Thus, the reflecting surfaces 42 a to 42 e of the reflector member 42 can be disposed close to the peripheral surface of the design drum 34. For this reason, the light from the illuminating means 41 can be accurately illuminated without diffusing to the surroundings, and it is possible to improve the effect of illumination. Furthermore, the light emitted from the LED 41a is received, the reflector member 42 is surface-emitted, and the symbols displayed on the symbol stop lines T are illuminated from the rear side, thereby increasing the width of the symbol drum 34. Even so, the entire symbol of the symbol stop line T can be brightly displayed with uniform brightness, and there is no possibility that the production effect will be reduced.
