Abstract: A serial scanner apparatus, correction method thereof, and storage medium for performing bi-directional reading with high precision and greatly improving the reading speed. A carriage is first driven in the forward direction, then reversed, and driven in the backward direction. The carriage is accelerated until the speed reaches a predetermined velocity v1. When the predetermined velocity v1 is reached, the carriage is driven at constant speed. In the head portion of the constant-speed driving area, a correction area (reference correction area), having the same distance as that of the correction area for forward driving, is provided. With the use of an area (actual correction area) obtained by adding an area for correction time stored by a controller unit to the reference correction area, read-start timing is adjusted and the bi-directional error is corrected.

Abstract: In a recording apparatus, a charging function is turned on when it is detected that a recording head is capped. It is thereby possible to automatically prevent charging during periods in recording processing when a motor and the recording head are driven.

Abstract: A data receiving apparatus which performs a handshake reception to set a busy signal upon reception of data and reset the busy signal upon storage of the received data in a buffer. The apparatus includes a busy extension unit and a reset control unit. The busy extension unit is for extending the set busy signal by a predetermined time period and resetting the busy signal after expiration of the predetermined time period, when a free capacity of the buffer becomes smaller than a first value in process of performing the handshake reception. The reset control unit enables the busy extension unit to reset the busy signal after expiration of the predetermined time period, if the free capacity of the buffer does not reach a second value during the predetermined time period, and for disabling the busy extension unit and resetting the busy signal prior to expiration of the predetermined time period, if the free capacity of the buffer does reach the second value during the predetermined time period.

Abstract: A printer has an electric power supply controller which controls electric power supplied to an indicator indicating a state of the printer so as to prolong a driving time of the printer, which is driven by a battery. When the apparatus is set to an on-line state using an on-line key, electric power is initially supplied to an on-line LED, which indicates the apparatus is in the on-line state. Afterwards, when a predetermined time period has passed, the supply of electric power is cut off to the on-line LED, whereby the consumption of electric power supplied to the indicator can be minimized.
