    摘要: A recording apparatus has a main body case housing a printing head. A recording-paper insertion slot is formed in the upper surface of the case and a recording paper discharge slot is formed in the side surface of the case. A pair of stop levers are mounted on the upper surface so as to be pivotable between standing and horizontal positions. A part of the upper surface is used as a continuous-recording-paper receiving portion on which the recording paper is placed and is led to the insertion slot. The standing stop levers contact the insertion-slot-side end of the recording paper to hold it in its predetermined posture or position and restricts the movement of the recording paper toward the insertion opening.

    摘要: A transmission device capable of reducing the information amount of channel quality indicators (CQIs) without deteriorating throughput. In the device, an upper bit transmission control unit (104) sets the transmission intervals between upper bits of the CQIs inputted from an S/P conversion unit (103) to be longer than the transmission intervals between lower bits of the CQIs, and a lower bit transmission control unit (105) sets the transmission intervals between the lower bits of the CQIs inputted from the S/P conversion unit (103). Then, a transmission unit (107) transmits the CQI on the basis of the transmission intervals respectively set by the upper bit transmission control unit (104) and the lower bit transmission control unit (105).

    摘要: A communication system enabling significant reduction in delay in handover between MAPs without increasing the number of MAPs to install. In the communication system, MAP(101) issues a Router Advertisement to AR(111) to AR(118). Particularly, MAP(101) assigns a plurality of Router Advertisements of a source of care-of address (RCOA) to register with HA to AR(118) of a cell on either side of a boundary of areas for each MAP. MN(107) receives a Router Advertisement transmitted from AR that is a communicating party among AR(119) to AR(126), and using the Router Advertisement, generates care-of addresses, RCOA and LCOA. AR(111) to AR(118) transmit the Router Advertisement RA generated by MAP(101) to MN in communication. Further, AR(111) to AR(118) transmit the care-or-addresses, RCOA and LCOA, issued from MN(107) to MAP(101).

    摘要: There is provided a transmission device capable of preventing increase of retransmission information or encoding redundant bit and improving a throughput in a MIMO communication method. In this device, an encoding unit (130) subjects data transmitted from a first transmission antenna (110) and a second transmission antenna (120) each formed by a plurality of antennas, to encoding processing all at once. Modulation units (113, 123) modulate the data encoded by the encoding unit (130) for each of the first and the second transmission antennas (110, 120). Transmission units (115, 125) process the modulated data so that it can be transmitted from the corresponding first and the second antennas (110, 120). A transmission control unit (160) performs transmission control of the data transmitted from the respective antennas (110, 120). When retransmitting data, the transmission control unit (160) retransmits the data transmitted from a transmission antenna having a smaller number of antennas than the first and the second antennas (110, 120).

    摘要: A control section (110) recognizes the type of data included in a transmission signal and outputs a control signal (C1) to an S/P conversion section (101) and a spreading control section (107). The S/P conversion section (101) apportions a specific type of data output from the control section (110) to different transmission systems. Spreading sections (102, 103) carry out spreading processing on the specific type of data output from the S/P conversion section (101) with different spreading codes assigned thereto under the control of the spreading control section (107). The data output from the spreading sections (102, 103) is transmitted by radio through addition sections (104-1, 104-2), transmission sections (105-1, 105-2) and antennas (106-1, 106-2). In this way, it is possible to improve the reception performance on the receiving side for specific data while maintaining the transmission efficiency of an MIMO communication system.

    摘要: A transmission control section 101 temporarily stores a transmission signal, outputs the stored transmission signal to a coding section 102 and outputs transmission timing information to a counter section 107. A preamble insertion section 104 inserts AGC preambles corresponding to the number set by a preamble number control section 110 into the transmission signal. The preamble number control section 110 compares a transmission time interval input from a subtraction section 109 with a threshold, decides to insert ten AGC preambles into the transmission signal when the transmission time interval is equal to or greater than the threshold and decides to insert five AGC preambles into the transmission signal when the transmission time interval is smaller than the threshold. By so doing, it is possible to make the transmission efficiency compatible with the error rate characteristic.

    摘要: Synchronization symbol insertion section 102: inserts a synchronization symbol into a signal digital-modulated by modulation section 101. 0 symbol insertion section 103 inserts a 0 symbol into the signal with the synchronization symbol inserted. The signal with the synchronization symbol and 0 symbol inserted in this way is sent to IFFT section 104 to be subjected to an IFFT calculation. Then, guard interval insertion section 105 inserts a guard interval into the IFFT transformed signal waveform. Then, the signal with the guard interval inserted in this way is D/A-converted by D/A converter 106. The D/A-converted signal is subjected to normal radio transmission processing and then transmitted.
