Around the periphery of a rotary disc which is manually turnable and on which coins are placed, there is formed a generally arcuate coin conveying passage which has a coin intake port. In this coil conveying passage, there are formed a plurality of sorting holes for sorting and dropping coins sequentially in increasing order of diameter from the upstream to the downstream. There is also provided a conveyor belt which has an annular shape when viewed from above and which is turned in synchronism with the rotary disc by intermediate gears, and so as to press and convey the coins. By coin sorting means arranged between the intake port and the sorting hole on the most upstream side for counting the coins passing by and measuring the diameters of the coins, a preset count is detected in a batch processing mode.

The invention relates to a lighting device, a liquid crystal display device and an electronic device; miniaturization and thin type of a light source unit can be realized in a vertical typed lighting device. The lighting device is a so-called vertical type lighting device, and comprises a circuit board and light source units of a plurality of light sources connected with the circuit board. Particularly in the light source unit, each light source is allocated on the circuit board in a manner that at least part of the light source is positioned on the width direction of the circuit board or the internal part of the circuit board. Concretely, each light source is allocated on the circuit board in a state that at least a part of base material composing each light source enters run-through holes arranged on the circuit board. Therefore, at least a part of each light source is partially overlapped with the width direction part of the circuit board or the internal part of the circuit board. Thus, the width of the light source unit can become thinner compared with the light source unit formed by allocating light source on the circuit board.
