Abstract: A recording apparatus including a recording device for recording line of images on a recording medium, and a feeding device having a stepping motor for feeding the recording medium in a feeding direction perpendicular to the recording lines. The apparatus has a signal generator for generating a timing pulse in timed relation with the start of recording of each recording line so that the recording of each line is started in response to the timing pulse. Further, the stepping motor is stepped to feed the recording medium from one line to another, in response to the timing pulse, such that the stepping of the motor from one excitation phase to the next produces an incremental feeding distance of the medium which is equal to 1/n of a line spacing of the recording lines, where n represents a positive natural number.

Abstract: A pedometer which has a walking sensor for detecting a walking by the vibration of a walker's body, a counter for counting the number of walker's walking steps from the walking sensor, an indicator for indicating the value of the counter, a walking reference signal setter for storing a walking reference signal arbitrarily set in advance by the walker, a walking reference signal generator for generating a walking reference signal set by the walking reference signal setter, and sound producing unit for producing a sound upon reception of the output of the walking reference signal generator. Thus, the pedometer can measure a walking reference signal arbitrarily set in advance by a user or a pitch of user's walking when he actually walks with the pedometer by sounding the result as the walking reference signal to give the standard of the strength of his walking motion to the user, thereby providing the walking motion with high motion efficiency.

The cartridge unit includes a first and a second frame which are pivotable about a rotation axis of the drum relative to each other, and a biasing member for biasing the two frames to thereby hold the frames in a first relative angular position. The housing body includes a portion for holding the cartridge unit such that the two frames are held in a second relative angular position, which is established by pivoting the two frames from the first relative angular position against a biasing action of the biasing member. The first and second frames each having holes or openings that are initially misaligned, cooperate in an overlapping fashion to provide at least one opening through which a portion of the drum is exposed outside the frames, when the frames are placed in the second relative angular position.

The fixing apparatus comprises a detector for detecting the temperature at or in the vicinity of the heat source; an operating circuit for operating the heat source when the detected temperature is lower than a required temperature; a device for notifying an operator that the temperature of the fixing apparatus has reached a temperature required for the fixing operation; and a timer which starts to count from the start of operation of the heat source. When the required temperature is reached, the timer is reset, and when operation of the heat source is restarted, the timer starts to count again.
