A clock generating circuit includes a first delay circuit array, which has a plurality of delay circuits, for measuring delay of an input signal, and a second delay circuit array for delay-replay having a plurality of delay circuits and being arranged in a direction opposite a direction of signal propagation in the first delay circuit array. In the image reading unit, a heat dissipating member for controlling a temperature of the image sensor is attached to one side of the circuit board, and a shield member for reducing a noise is provided on the other side of the circuit board. The medicine receiving chamber is arranged to be moved in a one section from the standby position to the discharge position so that entire of the lower opening portion of the medicine receiving chamber is within the upper opening portion of the upper body. The signal adjusting and selecting circuit couples the signal pin to the setting judging circuit and adjusts the external input signal into the setting signal according to the setting device in a first state, and couples the signal pin to the core circuit in a second state. Once the braking force is sufficiently reduced, the user may rotate the seat until the desired rotational orientation is attained. The single-pack or two-pack ink has a viscosity lower than 50 Cp at the application temperature, a surface tension lower than 80 dyncm at the application temperature, and a glass transition temperature of cured ink of greater than 120\xb0 C.
